Scottish surgeon, anatomist and physiologist Charles Bell died #OTD in 1842.
Charles Bell is perhaps best known for his description of a condition now known as "Bell's Palsy," which is characterized by muscle weakness that causes one half of the face to droop. He also formulated the Bell-Magendie Law. His works, including "The Anatomy of Expression in Painting", explored the ways in which emotions were expressed through the muscles of the face, blending art, anatomy, and observation.
For our anniversary my girlfriend got me a preserved sheep heart and I got her a vintage lobotomy pick.
We're less Romeo & Juliet and more Gomez & Morticia. 😛
I bet one of you will please be able to tell me, what is this part of a reptile's anatomy called? And what is it, a flap of skin, a blood vessel, something else?

“Quick” Nyctosaurus Doodle Please leave a like if you enjoy this style! I’ve just started to understand how vertebrae look in 3D, and I have a LOT more to understand. To add more to the pile, pterosaur cervical vertebrae have unique joints, and it hurts my brain without physical sculpts or scans. If you have any info that might be helpful, please feel free to reach out! #nyctosaurus#pterosaur#rubberhose#taxidermy#vertebrae#anatomy#cartoon
During a short up and down Flight 72, Mars helicopter Ingenuity lost its comm link with rover Perseverance. NASA engineers are working on restoring it.
This follows Flight 71 on Jan 6 which made an emergency landing 35 seconds into a 125 sec flight; apparently the relatively featureless sandy terrain proved difficult for its navigation system.
Meanwhile, Voyager 1 is still sending garbled data.
How could sand ripples on Mars have potentially caused Ingenuity's rotor blades to get lopped off so badly?
The foam core + carbon fiber rotor blades are 1.21 meters in diameter, rotating at 2,400-2900 rpm. At 2,400 rpm, the tips of the blades are moving at a whopping 152 m/sec or 547.4 km/h! At that speed, any obstruction will cause the relatively brittle blades to break.
This is a rendition of a 6-day-old chicken embryo. It's a model I made for a project for a client. I took it as a base for an animation of the development of a chicken embryo from first division to hatching. That will take some time though ;-)
Heading off to the first in-person conference of the year. You'd better believe I've packed and am wearing the good masks for this.
Talking at the conference on developmental collisions between upper molars. A bit of a theme change to my more recent conferences where I've been telling people all about the fun you can have x-raying old documents.
